#
# This file is part of mbed TLS (https://tls.mbed.org)
#
# Copyright (c) 2016, ARM Limited, All Rights Reserved
#
# Purpose
#
# Executes the basic test suites, captures the results, and generates a simple
# test report and code coverage report.
#
# The tests include:
#   * Unit tests                - executed using tests/scripts/run-test-suite.pl
#   * Self-tests                - executed using the test suites above
#   * System tests              - executed using tests/ssl-opt.sh
#   * Interoperability tests    - executed using tests/compat.sh
#
# The tests focus on functionality and do not consider performance.
#
# Note the tests self-adapt due to configurations in include/mbedtls/config.h
# which can lead to some tests being skipped, and can cause the number of
# available tests to fluctuate.
#
# This script has been written to be generic and should work on any shell.
#
# Usage: basic-build-tests.sh
#

# Abort on errors (and uninitiliased variables)
